the pressure medium lines are short-circuited with one another and also those to the two chambers 78 and 79 of the cylinder-piston arrangement 76 leading pressure medium lines are short-circuited with one another. This allows the sleeve with the aid of the operating handle 66 in a desired Position sdiieben, either for hand-controlled operation or to make a desired position, which then through Transition from switching position III In switching position II the additional switching valve 80 is locked.

In the embodiment according to FIG. 10, the emptying device contains two identical lifting and tilting devices 20a and 20b. For both lifting and tilting devices 20a and 20b there is a common one Control device provided, which makes it possible to selectively each of the two lifting and tilting devices 20a and 20b to operate independently of the other for emptying smaller garbage cans or both lifting and tilting devices for Emptying of larger rubbish bins to empty together in synchronous operation. Each of the two lifting and tilting devices 20 and 20a is equipped with its own gripper 37 and its own additional locking device 41. Independent of the respective mode of operation of the two lifting and tipping devices 20a and 20b, the grippers 37 are in their Movement and mode of operation of the gripper 37 of the respective other lifting and tipping device independently. Likewise is the additional Locking device 41 of each of the two lifting and tilting devices 20a and 20b of movement and operation the additional locking device of the other lifting and tipping device independently.

FIG. 11 shows an embodiment of the emptying device in which a Support plate 32c about twice the width than the support plate 32 in the device according to Figure 1 and an abutment plate 34c, likewise about twice the width as the abutment plate 34 in the device according to FIG. 1 is provided

are. In a device according to Figure 11 can therefore two smaller garbage cans are taken up next to one another by the carrier plate 32c and emptied together. Like Figure 11 shows, this lifting and tilting device 20c has two independently attached and movable grippers 37 and two also independently attached and operable additional locking devices 41. on In this way, with a lifting and tilting device 32c according to FIG. 11, two different garbage bins can be made at the same time Systems, for example a garbage can 50 with a smooth front wall 53 and a garbage can 55 with a long front wall Vertical groove 56 are emptied at the same time. While the gripper 37 at the location receiving the garbage can 50 in the passive position is pressed and the additional locking device 41 is not actuated at this point remains, the gripper 37 engages at the point receiving the garbage can 55 in the vertical groove 56 and under the support web 59, and the additional locking device 41 is actuated there to be in the vertical groove 56 behind the To grip the locking web 58 of the garbage can 55.

In the exemplary embodiment according to FIGS. 12 and 13, the basic structure of the lifting and tipping device according to FIGS. 1 and 2 is assumed. However, in order to save the switchover requirements on the actuating device 46, the additional Locking device 41 is provided with an actuating rod 81 which can be telescoped axially against the action of a spring. This operating rod is hinged at its lower end at 47 to the locking lever 82 and at her upper end in a horizontally arranged crossbar 83 rotatably mounted between the upper pair of links 24 attached. When emptying rubbish bins 50 with a smooth front wall, as in the examples according to FIGS. 1 to 11 the gripper 37 is pivoted from the smooth front wall of the garbage can into the passive position. When panning up the link pairs 24 and 25 approaches the crossbar

the pivot axis 42 of the locking lever 82, however, the smooth front wall of the garbage can 50 continues to pivot outward of the locking lever 82 or the locking hook 44 against resistance. This will cause the outward pivoting the locking lever prevented and the telescopic actuating rod is axially compressed against spring action .

When emptying garbage cans 55 with a long front vertical groove 56, the locking lever 82 engages with the Locking hook 44 in the vertical groove 56 behind the locking web 58. Since, however, the actuating rod due to their axially resilient telescopic training is not suitable that in the tilting position of the garbage can to support the load exerted on the locking hook and the locking lever 82 via the locking web 58, a counter-locking lever designed as a gravity lever is pivotably mounted on the locking lever 82, during the tilting movement of the tilting support 23 via a shell-shaped, solid one attached to the tilting support 23 Support element 85 is pivoted and thereby transfers the load from the locking lever 82 to the tilting support 23. However, the counter-locking lever 84 can only pivot over the support element 85 when the locking lever 82 is pivoted out into its locking position has been.

The actuation of the additional locking device is independent of the movement and in this example Position of the gripper 37. Therefore, the same locking processes also occur when a garbage can 60 is emptied with a short vertical groove 56 at the front, in which the gripper 37 is pivoted into the passive position is, but the locking lever 82 with the locking hook 44 in the vertical groove 56 behind the Locking web 58 can pivot.

In the example of FIGS. 14 and 15, the Basic structure of the lifting and tipping device according to FIGS. 1 and 2 assumed. The gripper 37 has the same in this example Structure as in the example of FIGS. 1 and 2 and is also in the same way as there around a horizontal axis 38 limited freely pivotable to pivot between a gripping position and a passive retracted position to be able to.

The additional locking device 41 in this case has a two-armed locking lever 86 which is attached to the a lever arm carries the locking hook 44 and is designed as a gravity lever 87 on the second lever arm. In addition to the locking lever 86, the additional locking device 41 has a counter-locking lever 88, which is mounted on the tilting support 23 about a horizontal axis 89, and a counter-locking element 90 wearing. As can be seen from FIG. 16, the locking lever 86 pivots due to its gravity arm 87 in the initial stage of the tilting movement of the tilting support 23 from its closed position. withdrawn position with its locking hook 44 behind the locking web 58 in the vertical groove 56 of the garbage can 55 or the garbage can 60 in the position engaging behind the locking web is the other Pivoting movement of the locking lever 86 is impossible, so that it is in the position relative to the tilting support shown in FIG 23 stops. At the same time as the locking lever is pivoted, the counter-locking lever also pivots 88 about its horizontal axis 89 until the counter-locking element attached to the counter-locking lever 88 90 along an insertion edge 91 into an abutment receptacle formed on the locking lever 86 92 arrives. When this position is reached, the locking lever 86 and the counter-locking lever 88 are locked together in such a way that they can only be released from each other again when the tilting support 23 is the last

Performs phase of its tilting back movement. In the example of FIGS. 15 and 16, too, the actuation of the additional The locking device 41 is independent of the actuation of the gripper 37. Unless garbage cans 50 with smooth Front wall are emptied, the locking hook is prevented by the container wall 53 from pivoting out. if Garbage cans 55 with a long front vertical groove 56 and garbage cans 60 with a short front vertical groove are emptied the locking lever 86 has the option of pivoting out, regardless of whether the gripper 37 takes effect or not.
